ELECTRIC GASeLIGHTING DEVICE AND GAS-COCK.

SPECIFICATION forming part o Letters Patent No. 384,796, dated June 19, 1888.

Application filed September 22, 1887. Serial No. 250,393. (No model.)

.To @ZZ whom itmay concern:

Be it known that we, WILLIAM TAG and SAN- FORD C. SMITH, citizens of the United States, residingin the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvementin Electric GasLighting Devices, which improvement -is fully set forth in the following specification and ac companying drawings.

Our invention relates to improvements in electric gas-lighting devices; and to this end it consists in a novel attachment to the tip for preventing the electrodes from sparking on their back-stroke, and to prevent grounding ofthe battery when the gas is turned down. This attachment is in the nature of a pivoted rider, which allows the electrodes to contact when the gas is turned on, and causes the moving electrode to ride over the fixed electrode when the gas is turned off, or when the movable electrode returns on the back-stroke.

The invention-further consists in the combination and arrangement of parts, as hereinafter set forth and claimed.

It will be better understood by referring to the accompanying drawings, in which Figure l represents a side elevation, showing the several parts in action. Fig. 2 represents an end elevation of the same. Fig. 3` represents a vertical section on line w av, Fig. 1. Fig. 4 is a detailview of the rider Yfor the movable electrode. Fig. 5 is a side elevation of the movable electrode and the hand lever for manipulating it, and the gas-cock.

Similar letters of reference indicate corre# sponding parts in the several figures.

A is the gas-pipe; B, the burner screwed thereto in the usual manner, and Tis the tip.

C is the cock, fitted in its socket C' from one side only, as' shown, thus leaving less chance of leakage and making a neaterappearing burner.

D is a stout metallic arm having at its lower end a hole, g, adapted to slip over the shouldered end of the cock C when in place,

and held in place against the burner by a screw,

E is an arm iixed to the cock by a square socket, e, and screw I, and adapted to open or close said cock. y

F is a movable electrode of wire, of .wellknownconstruction, affixed to the upper part of the swinging arm, and adapted to contact with the fixed electrode G,attached to a band of usual construction, and insulated, as shown, from the burner.

w w are the wiresrunning from the battery. (Not shown.)

a and b, Fig. 4, are two stops on the arm D, to limit the throw of the arm E by the lug d, as will be understood on inspection of Figs. 4 and 5.

The operation is as follows: On the `forward throw of the arm E (see Fig. l) the cock is opened and the movable electrode rides up theinclincd plane of the tilting lever or rider K andtilts it to theright, thus coming in contact with the lixed electrode, thereby pro ducing a spark. It passes [on and over said rider, which latter assumes avertical position, as sh own in Fig. 4. Ii', now, the gas be turned off, the movable electrode on its back-sweep abuts againstv the square shoulder t, which causes said movable electrode to ride over and I free of the fixed electrode, thus avoiding a spark, and hence unnecessarywaste of battery. If the gas be turned down, a like action takes place, and it is not possible to ground the battery by operation of the cock. The adjustment of the cock C is readily made by screw L and arm D, as will be understood on inspection.

We are aware that it is not new to provide electric gas-lighters with means for preventing sparking of the electrode, and we do not there fore claim such, broadly; but

What we do. claim as new, and desire to secure by Letters Patent, is-

1. In an electric gaslighting device, the combination of a stationary electrode, a pivoted movable electrode, and a pivotedrider in the path of said movable electrode, adapted to permit the electrodes to contact in the ad- 'vance movement of the movable electrode, and to prevent such contact on its retrograde movement, substantially as described.

2. In an electric gas-lighter, a listed electrode and a movable electrode, in combination with a fixed support or arm carrying a weighted rider, for preventing Contact of thc electrodes on the back action of the movable electrode, substantially as described.

8. In a gas-lighting device, the combination of the fixed electrode and the movable electrode attached on an arm fixed to the gas-cocl ,witl1 a tilting rider lying in the path of the movable electrode and pivoted to an armwhicli in turn has a bearing against the cock and holds it in place, substantially as described.

4c. A burner with an adjustable cock, in combination with an insulated xed electrode secured'to said burner, an actuating'arm of the cock carrying the movable electrode, and the adjusting `arm for the cock carrying a WILLIAM TAG.m S. C. SMITH.
